What idea was central to the sub-saharan african social structure?

The correct answer is kinship system

The kin-based system was a dominant form of social organization in sub-Saharan Africa. Under this system, culturally defined relationships between individuals who were considered as related was the most important organizing principle in the society

it is a part of john locke's natural rights popular during the age of enlightenment that people had inalienable rights to life, liberty and property. this was reflected by thomas jefferson in his declaration of independence as rights to life,liberty and the pursuit of happiness.

another line in the declaration of independence is that people have certain rights just because they are human. humans are capable of obeying the three natural rights john locke mentioned making them governable by these laws and therefore entitled to these rights as well.
